A great tool which can allow you to easily create graphic adventure games.
The program takes a script file that defines rooms and objects, assets like sprite and character files along with a simple (I hope) programming language, and hopefully it will get someone who otherwise would not program a game for 64 to do so.
You can download this tool for free, along with the example programs and a very detailed 32-page .pdf manual.
